Larry - thanks for the link to the source for the spawn() APIs.  It works
perfectly on my 32-bit install (where, as it happens, the fork() issue 
never shows up either). 

However, on my 64-bit install, the spawnv() call is returning with an 
error -- 'No such file or  directory' -- when I try to spawn /bin/sh.
I have attached the output from 'strace' on this process. If you look at
line 602, I think you can see where the exception gets generated. Can 
you see what is going on? I tried to create a simple test program that
shows the problem, but (so far) they all work. Thanks.

Steve
